1. An image processing device, comprising:
circuitry configured to:
not correct a level of a target pixel of an image in a case where the level of the target pixel is smaller than a first threshold value,
wherein the image includes a first peripheral image around the target pixel with the target pixel as a center; and
correct the level of the target pixel of the image in a case where the level of the target pixel is larger than a second threshold value, wherein
the second threshold value is larger than the first threshold value, and
the correction is based on a low-frequency component in the first peripheral image around the target pixel.
